You need some ducks!

The size of a quarter curled up? That's a pretty large grub! Are they junebug grubs I wonder? You could use beneficial nematodes as an organic method for controling them. It might be getting about time for you to apply them for this year if you're in zone 9. Also, I'm thinking that maybe since you just established your garden last year, maybe they were just there eating the lawn until you removed it and put a garden over them... as you keep the garden established, the adults may preferably lay eggs elsewhere than your (to them) rather barren garden and the problem will lessen.

In my old garden I used to find Japanese and Asiatic Garden Beetle grubs fairly often and I kept them under control mainly by picking them out whenever I found them and throwing them for the mockingbird to eat. That was pretty satisfying. I did apply the beneficial nematodes the first year, and I did see fewer of them the next year, which is when I switched to the hand picking method. I am sure there are other ways too. Good luck!

Rather than just start dumping on various chemical and/or "natural" solutions, I'd contact your local county extension to see exactly what they are and how best to treat them. Good luck.

sunnibel7- When we moved in there was nothing but dirt & Arizona sand. The only other thing is cactus & a tree (not sure what kind) from the neighbors yard, that is by our garden. The south side of the yard had some weeds but not much. After we found the grubs in the garden we started digging alittle in other parts and didn't find as many (1 or 2) or none anywhere else. I've read about the nematodes I need to find out where they have them here in Tucson.

Steve- I'll look into that too. They are vicious little things. I'd just hate to lose all of our veggies again.

LOL! Then it must be the other way around and your garden is like an oasis in the desert to them! :) For some reason I was imagining you down in Florida, but Arizona is a little different. Anyway, I got my nematodes from Arbico. If memory serves me correctly they are in New Mexico. I do like Steve's suggestion, and it is even possible that your local ag. school has a fact sheet or some such online. I know I look up info. from UMD and UVA frequently. Cheers!

Lol, it would be just my luck that they LOVE my garden. I emailed the UofA and was asked to take some into their office. And of course as soon as I got that email I have found none! Argh, will keep searching and get to the bottom of this. Thank you!
